Intel allows BIOS or the OS to enable or disable some CPU fueatures via IA32_MISC_ENABLE. I have machines that don't enable fast strings or monitor/mwait in BIOS, so do it on bootup instead.
Changes from v3: - Don't display CPU index (and therefore don't break !SMP build) - Don't display "Failed to enable..." when kmemcheck is on
Changes from v2: - Don't linebreak printk messages (for ease of grepping) - Use printk_once - Update the "Disabled fast string operations" message
Changes from v1: - Display FW_WARN messages. - Don't change the kmemcheck message. - Improve the fast string comment. - Improve the changelogs.
Andy Lutomirski (2): x86: Enable fast strings on Intel if BIOS hasn't already x86: Enable monitor/mwait on Intel if BIOS hasn't already
